I don’t recall changing the margin setting in Page Setup, but this morning I found all the margin settings, top, bottom, right, and left, set to 62 picas - so big that nothing would print, all I got was a single blank preview window.
Was this updated from an old 1.x project? That was a bug in an older beta, so I’m surprised it’s got through. It certainly shouldn’t happen for new projects. If it was updated from a 1.x project, try opening the original 1.x backup project in 1.x if you still have it around, and check the print settings there to see if they are odd there too.
